Solar Winds

In this segment, we'll hear about the solar wind, a gas plasma emanating from the sun at a million miles an hour. It forms a bubble around our solar system to protect against galactic cosmic rays. But new data suggest the solar wind is weaker than it's been since the beginning of the space age. We'll talk about what that might mean for our solar system, and life here on Earth.
